Introduction
An Alternative Trading System (ATS) is a non-exchange trading venue that provides a platform for buyers and sellers to meet and trade securities. In the United States, it is comparable to the Multilateral Trading Facilities (MTFs) found in Europe, offering similar functionalities but differing in regulatory structure.
Historical Context
ATSs emerged in the late 20th century as part of the evolution of electronic trading. They were created to offer more flexibility, anonymity, and often lower trading costs compared to traditional exchanges. The regulatory landscape began to formalize with the SEC’s Regulation ATS in 1998, which set forth the requirements for ATSs in the U.S.
Types/Categories
- Dark Pools: These ATSs provide anonymity, allowing large institutional orders to be executed without revealing the details to the public market.
- Electronic Communication Networks (ECNs): These are automated systems that match buy and sell orders for securities in the market.
Key Events
- 1998: SEC introduces Regulation ATS, providing a formal framework for the operation of ATSs in the U.S.
- 2000s: Growth in the use of ATSs, with an increase in market share and liquidity.
- 2018: Amendments to Regulation ATS to enhance transparency and oversight.
Detailed Explanations
Regulation and Functionality
ATSs are regulated under Regulation ATS by the U.S. Securities and Exchange Commission (SEC). While they perform many of the same functions as traditional exchanges, they are not subjected to the same level of scrutiny and operational requirements.
Mathematical Models
ATS operations often employ sophisticated algorithms to match buy and sell orders. These algorithms are designed to maximize efficiency and minimize market impact, enhancing the trading experience for participants.
